Integration issue with BBB app

[keithkhl]

I have used Social Login for Azure Auth by Custom OpenID Connect option.
It has been working flawlessly, until recently I have trouble integrating BBB with NextCloud.

• Endless three loading dots of BBB for all users with OIDC's Azure credentials littleredbutton/cloud_bbb#305

As was mentioned in the other issue raised to BBB app, I cannot access BBB from NextCloud, and it only occurs to user accounts that use Social Login's Custom OpenID Connect.

For once, I thought I mis-configured, so I cross checked with my settings on Moodle where I mainly use BBB, but the settings are not different.

The only issue that I was able to see was 'Scope', but below is my scope and all are granted by admin at Azurre portal.

• openid profile email offline_access User.Read

I have also added all API permissions and token configurations, but nothing worked so far.

My suspicision is that from Azure to Social Login and eventually to BBB, some information were not delivered. Otherwise, it should work like what it does with non-Social Login accounts on NextCloud and Azure accounts on Moodle.

I tried to track what was missing, but browser's dev console is clean, and I cannot find any issue at least from NextCloud. The error log must be available in BBB server, but I have limited access. If you can help me where to look, at least, I will try dig deeper.
